Hi! I've been having issues running the K2 system on my 2018 BMW GS Adventure. I've installed it about 6 months ago.
The unit seems to create interference with the bike's electronics, which causes it to repeatedly go into limp mode. https://youtu.be/ySiEg28Ah8s .
After a couple of visits at my local BMW dealer, I was asked to disconnect the K2 as, in their opinion, it was the source of the problem. I ran without the unit being powered, no issues for a month. Reconnected it, same problem again.
I moved the K2 from the control unit located under the driver's seat to under the back seat. Same issue.
